INTERNL-COMBUSTION ENGINE.

Application tiled September 8, 1914. Serial No. 860,720.

To'all whom it may-concern.'

Be it known that I, ALRED G. COLLEY, citizen of the United States,

a residing at Richmond, in the county of Henrico and State of Virginia, have invented a new and useful Internal-Combustion Engine, of

- which the following is a specification.

` The present invention relates to improvements '1n internal combustion engines, one

object of the present invention, beingthe provision of a stationary engine in. which the-power cylinder and gas admitting and others of which permit free access for the removaland grinding of they intake and eX- haustvalves. i

A further object of is the provision Aof an internal combustion engine, the cylinder of which is surrounded by a jacket havingan enlarged portion with an openmouth, said jacket and enlarged 'zportion being adapted to contain water for il to cooling the cylinder, thus rendering it un:

lnecessary to provide ay circulating pump for causing the water to circulate, theheat from the cylinder causingthe 'proper circu-A lation within the tank.

With the' foregoing and other objects in view which will appear as the descriptio-n proceeds, the invention resides in the combination andl arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes lin the precise embodiment of the invention herein disclosed` can be made withinthe scope of what is claimed without departing from the spirit of the invention.

Inl the drawings-Figure 1 is a longitudinal sectional view through the cylinder and water jacket and chamber of the present invention, the same being taken through the intake valve thereof. Fig.` 2 is a cross section-taken on line 2-2 of Fig.v 1. Fig. 3 is a section taken on line 3-3 of Fig. 2.

Referring to the drawings, the numeral l designates. the power cylinder which is provided at its end, with the integral transversely disposed elliptical chamber 2, having the interiorly threaded port or opening 3in the axial line thereofand also coaxial with the/cylinder 1. lInsertible within lthis interiorly screw threaded opening 3 is the the present invention,`

1 plug 4 which carries the spark plug 5. Thus v by removing the plug 4, access may be had 4ltatented Dec. 28, 1915.

to the reduced chamber 2 of the present en- A gine.

' Formed in the upper portion of the walls ofthe reduced chamber 2, as clearly illustratecl in the drawings, is an interiorly screw threaded opening -4 ,for the reception of the.-

removable plug 5, while at the opposite side or parallel therewithas clearly illustrated in Fig. 2, is an interiorly screw threaded opening 6, fitted withV the removable plug 7. These plugs 5 and 7 4constitute a means for permitting of the'ngrinding, inserting and removal of the respective puppet valves 10' and 16, as will later appear.

The exhaustport 8 of the present )engine is located to communicate through the valve seatedportion 9 into the reduced chamber 2,

said valve seated portion I9 being controlled by the puppet valve 10, whose stem 11 is slidable through the adjustable sleeve 12 which is mounted in the interiorly threaded aperture 13 as illustrated in Figs.y 1 and 2. 1 The intake port 14 is in communication with 'the valve seated -p'ort 15 4controlled by the puppet valve 16, the stem 17 of which is slidably mounted in the sleeve 18'adjustably mounted in the interiorly screw threaded opening 19 and by this means both the valve stems 11 and 17 are coaxial with the respec-` tive openings 4 and 6, and are thus mounted for parallel movement. By this means no strain is placed upon the stems as would be the case Where the valves are through the side of the'chamber as both have vertical straight line movements. j

The mechanism for operating both valves is similar, being shown as operating the intake valve in Fig.' 1. To accomplish this, the spring-20 surroundsthe lower end of the stem.17 and is adjusted by means of the adjustable bushingor cap 21 adapted to beengaged by theiadjustable means 22 carried in the free end of the lever 2,3. This lever 23 is journaledat 24 in the base' 25 of the engine, vand carries aroller 26 at its opposite end. This rollerl is disposed for engage-4 ment by the lcam 27 mounted upon the transverse shaft 28 ixed to the gears 29 and 30 which are operated in timed relation tothecrank shaft 31. As usual the crank shaft 31 is connected to the piston-32 and to the power cylinder.

As clearly illustrated, instead of having a 'waterfcirculating system as usual to cool i the cylinder 1 and the chamber 2, a Water reservoir 34 having the enlarged mouth 35 to permit of therescape of steam therefrom and to prevent any excess pressure within the same is disposed to surround the cylinder l and portion 2 thereof, the reduced portion of the cylinder at 36 surrounding the'cylinder l adjacent the inner end thereother water circulating means is dispensed. with, thus producing anexceedlngly simple and inexpensive structure.

By arranging the valves as illustrated in Fig. 2, it is apparent that the same are .readily accessible through the opening 35 of the water tank 34: and that the valves may be readily inserted and ground or removed when desired.

What is claimed is:

An internal combustion engine, including a power cylinder having a. reduced transversely disposedchamber at one end,

said chamber and cylinder being disposed.

horizontally, said reduced chamber being provided with an intake and an exhaust port and with two oppositely disposed alined openings, plugs for sealing said openings, and an integral water jacket, sur.- rounding the greater portion of the cylinder and also the reduced chamber, the last mentioned openings being open into the jacket and said jacket being provided with a hand hole opening to permit access thereto.

In testimony that I claim the foregoing as my own, I have hereto aliXed my signature in the presence of two witnesses.
